SPRING-LEAF OILER.

Specification of Letters Patent.

Patented Aug. 31, 1920.

Application filed March 22, 1919. Serial No. 2214364.

To all who-m it may concern:

Be it known that .l, Fnnnnnron KLEIN- snrrrr, a citizen of the United rotates, resid ing at Indianapolis, Marion county, and State of Indiana, have invented and discovered certain new and useful Improvements in Spring-Leaf ()ilers, of which the following is a specification.

My said invention consists in certain improvements in the details of construction and arrangement of parts of oil containers and distributors for use on leaf springs, to provide lubrication between the leaves thereof and thus avoid friction, wear and noise common in the use of springs of this type which are not properly lubricated, and whereby the oil is directed into the crevices between the springs and prevented from wasting, all as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings which are made a part hereof, and on which similar reference characters indicate similar parts.

Figure l is a perspective view showing one end of a spring of the type referred to provided with one of my improved oiling devices.

Fig. 2, a cross section on the dotted line 2-2 in Fig. 1,

Fig. 3, a perspective view of the oiling device separately on a somewhat larger scale, and

Fig. 4, a detail. view showing the oil hole cover.

In said drawings the portions marked A represent the spring, and B the oilcr.

The spring A is of any common leaf spring type.

'l he oiler B consists of a casing comprising on inner shell 10 and an outer shell 11, substantially inverted U-shape in cross section and spaced a distance apart forming a central arched bolt chamber or passageway within the inner shell and a space between the two shells, which is filled with packing to a point indicated by the dotted line 12. The bottom and ends of the chamber between the two shells are closed the end closures having elongated channel bars or guides 13 extending each way therefrom with flanges let and 15 adapted to embrace the edge of the top leaf of the spring A. Narrow oil outlet openings 16 are formed at each end of the chamber and on each side thereof. A filling opening 17 is formed in the top of casing 11 which opening is normally closed by a plate 18 supported against the interior face of the casing on curved legs 19 and 20, as most clearly shown in Fig. 4, the cover 18 being supported on a spring metal bar extending from one set of legs to the other. In filling the chamber between casings 10 and 11 the spout of the oil can is forced against the cover 18 and the same depressed under the yielding of the spring bar to permit oil to flow from the oil can into said chamber onto the packing therein. As soon as the pressure of the spout of the oil can is removed the spring bar returns plate 18 against the inner surface of the casing 11 and closes the oil hole against the entrance of dust and dirt.

In operation the oilcr is mounted on a spring, as shown in Fig. 1, and held thereon by the clip 21 and clamping bolt 22, which is a usual part of the spring structure, and being supplied with oil, as above described, said oil gradually works through the pack ing and discharges through the outlet pas sageway 16 running down into the interior of the side guide bars 13 against the lower flanges 14: thereof, said flanges 14: serving as guides to direct the oil into the recess between the top leaf of spring A and the adjacent leaf and the overflow passing down over the edge of the spring and by the movement of the spring, while the vehicle is in operation, working its way in between the other leaves of the spring, keeping them lubricated for substantially their full length, as will be readily understood.

By this means the oil is given a wide distribution over the length of the spring so that it will not run down the sides of the clip 21 and waste, but will be distributed over a considerable portion. of the sides of the spring and find its way between the leaves and perform the function for which it was intended. Said flanges also serve the purpose of enabling the oilcr to be clamped to the spring at any point along the top leaf desired, the flanges fitting over the edges of the spring the lower flange between the leaves and holding the device in any position desired.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

1. An oilcr for leaf springs comprising an oil container having ends adapted to embrace the sides of the spring, said ends being provided with bars extending each Way from the oil container and formed with flanges adapted to embrace the edges of the leaf of rounding a central passageway and having closed ends and bottom with oil outlet pas 7 sages at saidends, a clamping bolt extending through said central passageway for securing said oiler in position, the ends of said chamber being provided With extension bars extending each Way from said chamber and adapted to-embrace the edge of the spring and serve to guidethe oil length- Wise of the spring from said container, substantially :as set forth.

cover mounted on the inside of said chamber and held over said opening by spring pressure, a packing in said chamber, closed ends with sideextension arms adapted to embrace the edges of the spring, said side extension arms being formed With flanges to guide the oil each Way from the oil container, substantially as set forth.

In Witness whereof I have hereunto set my hand and seal at Indianapolis, Indiana, this 18th day of February, A. D. nineteen hundred and nineteen.
